core pack is dealer upgrade UK
helloFrom my local beneteau dealer, S1 is standard and beneteau France will not upgrade or swap, its up to your dealer. May be different in u.sMy dealer will do the swap S1 for S1g at no extra as he can factor it into the boat price, you know how it goes !S1G is superior and if you use a C or E range radar plotter you will get MARPA functionallity and the also the AST.Friend of mine on his new Dehler 36 says it is well worth the upgraderegdsfranky
